HP-71b - Future "SD-RAM" Module - viable ?

[Garth Wilson]

J-F Garnier, it has been so long since I last used the 71 that I had to review how it handles the files, and I am reminded that it does make it easier than the 41cx does to do file operations at different locations and specify the location. What I use every day is the 41cx whose file operation commands are one set for XMEM, another set for HPIL, and if there were a module with MicroSD, it would have to be yet another set.

However, I have two tape drives, which I've used for both the 41 and the 71, and if one had the conversion to accept SD card (it wouldn't have to be MicroSD), the same drive could be used for both machines. (Actually I have a 75 also, but it was given to me in very beat-up condition, with no manuals, and I've never used it except to verify that it does work. Further, I have two 71's.)
